MultiSelectSegmentedControl - multiple selection segmented control

A subclass of UISegmentedControl that supports selection multiple segments.

No need for images - works with the builtin styles of UISegmentedControl.

Usage

Drag a UISegmentedControl into your view in Interface Builder.

Set its class to MultiSelectSegmentedControl.

Set an outlet for it, perhaps calling it something creative such as myMultiSeg.

Set the selected segments:

myMultiSeg.selectedSegmentIndexes = [NSIndexSet indexSetWithIndex:1];

Get the selected segment indices:

NSIndexSet *selectedIndices = myMultiSeg.selectedSegmentIndexes;

Get the selected segment titles:

NSLog(@"These items are selected: %@", [myMultiSeg.selectedSegmentTitles componentsJoinedByString:@","]);

If you want to be notified of changes to the control's value, make sure your ViewController conforms to the delegate protocol:

@interface MyViewController : UIViewController <MultiSelectSegmentedControlDelegate>

...and set the delegate, perhaps in your viewDidLoad method:

myMultiSeg.delegate = self;

You are notified of changes through the following method:

-(void)multiSelect:(MultiSelectSegmentedControl *)multiSelectSegmentedControl didChangeValue:(BOOL)selected atIndex:(NSUInteger)index {

	if (selected) {
		NSLog(@"multiSelect with tag %i selected button at index: %i", multiSelectSegmentedControl.tag, index);
	} else {
		NSLog(@"multiSelect with tag %i deselected button at index: %i", multiSelectSegmentedControl.tag, index);
	}
	
	
	NSLog(@"selected: '%@'", [multiSelectSegmentedControl.selectedSegmentTitles componentsJoinedByString:@","]);
	
}
